Struct TransactionSelector

pub struct TransactionSelector {
    pub begin: Option<TransactionOptions>,
    pub id: Option<Vec<u8>>,
    pub single_use: Option<TransactionOptions>,
}

This message is used to select the transaction in which a Read or ExecuteSql call runs. See TransactionOptions for more information about transactions.

This type is not used in any activity, and only used as part of another schema.

Fields

begin: Option<TransactionOptions>

Begin a new transaction and execute this read or SQL query in it. The transaction ID of the new transaction is returned in ResultSetMetadata.transaction, which is a Transaction.

id: Option<Vec<u8>>

Execute the read or SQL query in a previously-started transaction.

single_use: Option<TransactionOptions>

Execute the read or SQL query in a temporary transaction. This is the most efficient way to execute a transaction that consists of a single SQL query.
